Table: DISPATCHCONSTRAINT

DISPATCHCONSTRAINT

Name

DISPATCHCONSTRAINT

Comment

DISPATCHCONSTRAINT sets out details of all binding and interregion constraints in each dispatch run. Note: invoked constraints can be established from GENCONSETINVOKE. Binding constraints show as marginal value >$0. Interconnector constraints are listed so RHS (SCADA calculated limits) can be reported.


Description

DISPATCHCONSTRAINT is public data, and is available to all participants.
